The role of neuroglia in the development of drug dependence
Stratilová, Mária ; Novotný, Jiří (advisor) ; Chvátal, Alexandr (referee)
Drugs of abuse, such as opioids and amphetamines, represents nowadays a serious global problem which has economical, psychological, social and medical impact. Investigation of drug effects on the nervous system has been a subject of many studies during the last few decades. The interest in neurons regarding this issues is rather constant, but currently there is increasing number of studies focused on neuroglia and their role in drug addiction. Many studies demonstrated that glia are not only a part of neuropile and do not have only supporting function, but they play an important role in communication between neurons, participate in modulation of neurotransmission and could produce factors such as cytokines and chemokines. However, there is a not much information about the effect of drugs of abuse on neuroglia and the presumed role of these cells in the development of addiction in not quite clear. This review aims to provide a brief survey of current knowledge on this topic.

Changes in neuroglia in degenerative disorders of the central nervous system
Kirdajová, Denisa ; Zach, Petr (advisor) ; Hock, Miroslav (referee)
Neurodegenerative diseases are a serious disorders of the central nervous system characterized by neuronal loss with a subsequent damage of the brain. This damage may have diverse consequences like a gradual loss of memory and intellect, problems with musculoskeletal system and not least death. Causes of these diseases are not yet fully understood. In addition to neurons neuroglia also plays an important role in these diseases of the central nervous system. In neurodegenerative diseases are astrocytes, oligodendrocytes, microglia and NG2 cells involved in their many aspects. They participate in the protective as well as in the detrimental aspect of these diseases. This work, therefore, presents an overview of previously acquired knowledge of neuroglia in various types of degenerative disorders of the CNS (Alzheimer`s disease, Parkinson`s disease, amyotrophic lateral sclerosis, multiple sclerosis, Wernicke encephalopathy, HIV associated dementia, frontotemporal dementia, vascular dementia).
